I'm stuck on a question on a past exam paper that asks if a group $G$ is isomorphic to a subgroup $GL(2,\mathbb C)$. We are given the character table for $G$ which I've attached below. It's the last part of a question so I've already worked out that $G$ is simple and not soluable, but I'm not really sure where to start with this. I can't find anything in my notes that will help me.
If anyone could point me in the right direction I'd be very grateful.
The question is here, its Q2 part f.
